ANSWER No they didn't. They instead sent to Russia military forces which fought against the Bolsheviks.
The Bolsheviks were the red army. They fought against the white army. The white army was made up of the sailors from the former Russian navy along with other anti communist groups.
Just about everyone did. The Left Social Revolutionaries were supportive for a while and participated in government with them but eventually they wound up being traitors essentially. The main group within Russia that fought against the Bolsheviks however was the Tsarists, they were supported by the Right SRs and the Mensheviks. They were all soon supported militarily by over a dozen other countries like the US, UK and France. After the Left SRs left them, the Bolsheviks were left by themselves.
No, the Bolsheviks were not soldiers in the White Army. The Bolsheviks were a political faction that led the October Revolution and established the Soviet Union. The White Army, on the other hand, was composed of anti-Bolshevik forces who opposed the Bolshevik regime during the Russian Civil War.
They fought to overthrow the Provisional government and established communism in Russia.
Left-wing uprisings against the Bolsheviks happened in 1918.
